To all whom it may concern: Be 1t 1 rnown that I, SAMUELS. Woon- BURY, citizen of the United States, residing et Bradford, -in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Tank- Heaters, of which the' following is a s eciiication, reference being had therein to t e accom anylng drawing. l

y invention relates to improvements in tankheaters and pertains more particularly for heating tanks of crude troleum. s

'llhe object of my invention is to provide a device-of this character in which tanks of crude petroleum can be economically and unlformly heated causing the least amount of evaporation and whereby the oil is thor -oughly mixed, settled and heated preparatoxXnto delivery to ipe lines.

other object o my invention is to provide e more sim le cheap and effective device to laccomplis the results desired.

In the accompanying drawing Figure 1 -is a .side elevation of my improved device partly in section. Fig. 2 is an enlarged vertical sectional view partl broken away of the. burner heating rum. Fig. 3 is a pers active view of the mixing drum showing e lower end broken away.

end of the rod 2 is screw-t readed at 5 and.

. which the pipe 8 asses.

having a nut 6 screwed for a 'usting the rod up or down and also for allowing of its ready removal. The lower end of the sleeve is provided with a T- pipe 'oint 7 through he said i y extends outwardly ough the tank wrh e the Inner end lpasses inwardly throu h the side Wall 9`of t e mixing drum 10 an has its inner end Aturned upwardly at 11 the said drum being sup rted y the p.' e as shown. The drum own is od an e ongatediorm .and having-.its side wall 9 above the pipe 8 vided with two or more clips 12 and 12 which pass 'around the ipe or sleeve 3 and 55 steady and serve as a ditional supporting means for the drum.

The lower end of the drum 10 is provided with the horizontal outwardly extending flange 14 the urpose of which will be here- 60 ina-iter more lly described. The drum as shownlaes its upper and lower ends open,

While the up er end is provided with radially arranged inclined blades 15. The blades 15 are-intended to check the rapid ascension of the hot oil from heater to surface of tank Where rapid evaporation would take place, and mixing it thoroughly with the currents of cold liquid as it is drawn upwardly through the spreader, caused by the upward current ofheated oil,v and discharging it in a circular motion, giving the oil in tanks cirI cular circulation end still further mixing it. This with the downward circulation to take the place of oil drawn tolthe surface through Y circulator from the bottoni makes circulation quite complete.

Adjacentthe tank I provide my improved heater which consists of a base 16 ha. al

circular burner 17 mounted thereon. he 80 said burner having a vertical outer wall 1S 4and anoblique l.inner wall 19 provided with perforetions 20 which are arranged at an angle to the oblique well 19 and thus givesa circular motion to the gas dame coming in S5 contact with the heating cylinder at about the same angle es the lspiral ribs of the heater. This with my central suction draft at bottom and top causes the flames to hug or follow closely to the heating cylinder from bottom to top making a very economical heater in the consum tion of fuel. The burner has connected t ereto the oil or gassupply p1 21 which has the air lnlets 22 which supp y air to the burner and forms a Biinsen burner.

The eaidburner 17 is provided with e series ofi-upwardly extending members 23 which have at .their upper ende thev notcliee24 in which rests the' casing 26 ofthe heater. y VTlie heater is composed `of an outer metal casing 26 and inner reelay or brick lining-"27 es shown. The lower end of casin 1s flared outwardly as indicated at 2 8 to orm an 'enlarged rombustien space 29 Juistl above the'burnen :Iheu extends considera y the 19 brick I end ofthe casing 2,6

33. Previous to the lighting of theburner `and the tank 31 is amount of oil or and is provided at its upper end with a caj30.

xtendin upwardly through the center of the fire rick is a heatin `chamberl 31 which is of a length equal to t at of the fire brick and is preferabl cast and having conical shaped upper an lower ends32 and 33 which are screw threaded for cou ling the p s thereto, as will be hereina` er more llgr described. The said tank has cast thereon spiral ribs 34 which are of a width to extend out to and snugly fit the inner face ofthe re brick 27, and thus forming a spiral passage around the chamber. Connected to the u per end 32 of the chamber is a pipe 35 wlich extends through casing 26 and is connected to the pipe 8 and all of which forms the return pipe to the tank 1. The said pipe intermediate the tank 1 rovided with a cock 36 by means of which t e flow of oil through the pipe may be regulated or cut off. The ower en 33 of the chamber 31 has a pipe 37 connected thereto and extends downwardly below the base 16 and is connected to the tank 1 a distance above the bottom thereof.

by which t e oil to t e tank 31 may be regu-A lated or cut oli as desired.

In o eration the burner is lighted in any desire manner and the inner face 19 being obliquelyl arranged the jets extend at an angle and engage the lower end of the tank the cocks- 36 and 38 are o ened. The products of combustion, smo e and heat from the burner ass u wardly between the chamber and fille fire rick and are caused to encircle the tank, thus forming a long spiral passage 34 for the heat and cause'the oil within the chamber to become more thoroughly heated with the least possible as for the burner. The fire brick also retains the heat and causes a more thorough heating'of the chamber. The

' oil as. it becomes heated within the chamber 31 will cause a circulation thereof through the pi es 35 and 37. The pi e 37 supplying the o' from the tank 1 to the ower end of the chamber 31 while ipe 35 conveys the heated oil back to the tan 1. The pipe 35 as shown Ais connected to the pipe 8 which'discharges the oil into the drum 10 in an upward direction thus causing an upward movement of oil from-the lower end of the drum therethrough as shown andcausinga thorough mixing of I the cool oil in the tank with the heated oil from the pipe 8. The oil as itis driven upwardly through the drum strikes the oblique blades 15 which s read the oil in an upward and outwar direction and tend to thoroughly mix and cause a thorough circulation of the il within the tank 1 and mix the cool and heated oil whereby the whole body of oil is maintained at the same'temperatuiie. The drum 10 is a' suiicient distance from the bottom of the tank 1 to allow of any sediment to settle to the bottomof the tank and sup ly pipe 37 being above the bottom will not raw off -such sediment.

The flange 14 at the bottom of the -cylinder is to make more certain of drawing the colder oil from the sides of the tank and not from along the sides of the cylinder where theoil to some extent is warmer. 4,

Having thus described my invention what I claim and desire to secure by Letters Pat-r er and -extending through the tank, andinto the mixing drum and havin its end turned upward and discharging t e liquid in an u ward direction through the drum.
